In a car, engine oil is the primary component that drives the whole system. Taking proper care of the car's components will ensure that the vehicle runs smoothly and won't cost you a lot of money. However, today people get so engrossed in their lives that they cannot pay proper attention to the car. Even if they do so, they forget to glance at the engine oil and whether it must be changed or not.

You might see that when you need to find the best engine oil for a car, there are various kinds of oils that you can select from. Mineral oils used to be the only ones, but synthetic and semi-synthetic oils began to be used with time and technological advancement. Likened to mineral oils, these oils are better efficient.

Moreover, this article will discuss the pros and cons of using mineral oil and synthetic oil, the different grades of engine oil, and how you can find the best engine oil in India.

Engine oils: Pros and Cons

Mineral, synthetic, and semi-synthetic oils are the numerous standard types of engine oils.

  1. Mineral oils

Mineral oils are directly extracted from crude oil. It is the cheapest oil that is available for engines. It is suitable for drivers with fewer engine designs and those with a simple driving type.

Advantages- If you have an older vehicle, mineral oils are the best for you as they are a cheaper option designed specifically for these vehicles.

Disadvantages- Mineral oils offer minor protection, cannot be used in current vehicles, and can not withstand high-capacity temperatures.

  1. Synthetic oils

Synthetic motor oils are not extracted naturally. It combines mineral oil and some additives and is regarded as the finest oil for modern-day cars.


  • It has far more useful cleansing properties than mineral oils.
  • It can resist high or low-grade temperatures
  • It aids in the better flow of oil at the start of the cars and thus helps protect from wear and tear.
  • Synthetic motor oils have additives that improve their reduction process than mineral oils.
  • They have low oil viscosity, qualifying for a faster flow of oil.


  • Since it is more useful for cleaning, it can withdraw deposits from the surfaces of machines and thus facilitates leaks.
  • Synthetic motor oil is a costly product, and once refilled, it can command a lot to maintain
  • It is not suggested for use in newer cars as it can cause a problem.
  • Synthetic motor oil can generate a lot of environmental decay.
  1. Semi-Synthetic oil- Semi-synthetic engine oil is the amalgamation of mineral and synthetic oil.


  • It provides more useful fuel economizing than mineral oil gives cars.
  • The semi-synthetic oils have low friction and viscosity, making them easier to flow.
  • The semi-synthetic oils are slightly more expensive than fully synthetic oils and deliver the best engine life.
  • This engine oil provides a robust defensive mechanism and thus protects the engine from heavier loads and high temperatures.


Semi-synthetic oils show less degree of protection than those supplied by fully synthetic engine lubricants. Moreover, Engine oils are the lifeblood of the engines and are responsible for running the cars. It offers a combination of functions ranging from security to increasing fuel efficiency. Moreover, the best engine oil for cars is available, and you can also select the different engine oils according to their grades. Let’s examine the grading of the engine oils in particular.

Different grades of engine oil

Engine oils have been classified and given different grades based on their viscosity by the SAE (Society of Automotive Engineers). The engine oils have different viscosities. The inferior the viscosity, the faster the oil can flow and the more useful it is.

Now, the grades of engine oils can be classified into monograde and multigrade oils.

  • Monograde oils

These oils are used for a small temperature range and are usually preferred for older vehicles. According to its viscosity, engine oils can be further divided into two groups: A low engine oil viscosity is referred to as a W and is suited for winters, and a tall engine oil which does not end with W, is just for summers.

  • Multigrade oils

Multigrade oils are prepared for the most delinquent cars and can be used in all seasons. The viscosity grades of the multigrade oils consist of alphameric notations, e.g., 10W20, where 10 W is a low-temperature viscosity, and 20 is a high-temperature viscosity oil. Multigrade oil is more effective than monograde fats and less reactive to temperatures.
